Bump immutable from 3.8.3 to 4.3.9

[celiac747]

Summary

Bumps the root immutable resolution from 3.8.3 to 4.3.9.

immutable is not a direct dependency of any package — it is a transitive dependency of relay-compiler@12 / @ardatan/relay-compiler@12 (used by packages/nova-graphql-compiler), pinned through the root resolutions block.

Why the resolution bump alone isn't enough

immutable v4 changed Map#toArray() to return [key, value] entry pairs instead of values, which silently breaks relay-compiler v12 codegen (it produces malformed/empty schema input rather than erroring). To keep relay-compiler v12 working under immutable v4, both copies are patched to use valueSeq().toArray():

• lib/core/CompilerContext.js — documents(): this._documents.toArray() → this._documents.valueSeq().toArray()
• lib/codegen/CodegenRunner.js — baseDocuments.toArray() → baseDocuments.valueSeq().toArray()

This mirrors the fix in microsoft/graphitation PR #720. Patches are applied via Yarn berry's native patch: protocol (.yarn/patches/*.patch + resolutions wiring).

Changes

• package.json: resolutions.immutable ^3.8.3 → ^4.3.9, plus patch: resolution entries for relay-compiler@npm:^12.0.0 and @ardatan/relay-compiler@npm:12.0.0.
• yarn.lock: immutable now resolves to 4.3.9 (no 3.8.3 entry remains).
• .yarn/patches/relay-compiler-npm-12.0.0-*.patch and .yarn/patches/@ardatan-relay-compiler-npm-12.0.0-*.patch.

No beachball changefile — immutable is a resolution, not a published dependency of these packages.

Validation

• yarn install --immutable passes.
• On-disk CompilerContext.js and CodegenRunner.js for both relay-compiler and @ardatan/relay-compiler contain valueSeq().toArray().
• yarn lage build ✓ and yarn lage test ✓ (all green).
• nova-graphql-compiler relay codegen test passes end-to-end (generates Example_feedbackFragment.graphql.ts), confirming relay-compiler v12 works correctly under immutable v4.
